I suspect both of you have a failed main power supply, this model may not be well-protected against brownouts or surges.
The main supply is usually a separate board and if you remove the lower rear panel, look for a board that seems to be related to the AC line and has larger components than the other boards. Some of them will be cylindrical and others block-like.
Look for a board number since this is a component that is often outsourced and may not be from the same manufacturer in every set. Call the nearest service center to inquire about repair or replacement costs.
